The impact of public health services on the quality of life of migrants in China: an examination based on health records and health education.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPublic health services accessible to urban migrants not only directly impact their health status, but may also significantly influence subjective well-being. However, existing research predominantly focuses on objective welfare aspects (e.g. disease prevention and health management), while largely neglecting its impact on subjective well-being domains such as quality of life (QoL). This study bridges this gap by extending the analytical scope of public health services (including health records and health education) from objective welfare to subjective well-being domains, thereby providing novel insights into the formation mechanisms of health equity pertaining to migrants' QoL.
methodsCausal effect analysis was conducted using a cross-sectional dataset from the 2017 China Migrants Dynamic Survey (CMDS; valid sample size n = 154,586). Baseline estimates were generated using ordinary least squares (OLS) regression, while the conditional mixed-process (CMP) estimator and omitted variable tests were employed to correct for endogeneity issues related to health records and health education. Additionally, the Karlson-Holm-Breen (KHB) decomposition method was used to explore mediating mechanisms.
resultsEstablishing health records (β = 0.0186, p < 0.01) and receiving health education (β = 0.0192, p < 0.01) significantly improved the QoL of migrant populations, and these findings held after correcting for endogeneity. Heterogeneity analysis revealed that these positive effects were more pronounced among older generations, females, urban-to-urban migrants, and inter-provincial migrants. Further KHB mediation analysis identified significant mediating roles for health habits, health behaviors, social interaction, and local identity, with local identity contributing the largest share of the mediating effect.
conclusionGovernment provision of equalized public health services to migrants can significantly enhance their QoL. This process is primarily realized through mediating mechanisms such as improved health habits, shaped health behaviors, expanded social interaction, and strengthened local identity Therefore, we recommend incorporating public health services into the top-level design of migrant social integration policies as a crucial means to achieve universal health coverage and promote social equity.
